Generation of downburst outflow in a traditional wind tunnel using multi-blade flow control device

Advances in Wind Engineering
The thunderstorm downbursts impose a great threat to civil engineering structures and the experimentation for such nonsynoptic winds plays a significant role in the characterization and quantification of relevant aerodynamic loading.

Experimental Investigation of the Near-Surface Flow Dynamics in Downburst-like Impinging Jets Immersed in ABL-like Winds

Atmosphere, 2022
Downburst winds are strong downdrafts of cold air that embed into the atmospheric boundary layer (ABL) and produce intense horizontal outflow upon impingement on the ground.

Experimental Study of Downburst Wind Flow over a Typical Three-Dimensional Hill

Applied Sciences, 2022
To achieve a comprehensive understanding of a three-dimensional (3D) wind field and the speed-up phenomenon in a downburst wind flow over a 3D hilly terrain, a succession of laboratory tests utilizing 12 hill models with cosine-squared cross-section was ...

Oklahoma Downbursts and Their Asymmetry

Journal of Climate and Applied Meteorology, 1987
Abstract Doppler radar data collected each spring in 1979–1984 with the two Doppler radars operated by the National Severe Storms Laboratory (NSSL) are used to investigate the asymmetry of low-altitude divergent outflows of convective storm downbursts in central Oklahoma.

Three‐Dimensional Lightning Characteristics of Severe Convective Weather in Shanghai

Meteorological Applications, Volume 33, Issue 2, March/April 2026.
Using 2022–2024 ADTD data, this study analyzes 3D lightning in Shanghai's severe convection. Activity peaks in August and afternoon hours, varies by weather type, and concentrates spatially in Pudong and Chongming. Results provide key references for selecting lightning indicators in forecasting and warning systems. ABSTRACT Using ADTD three‐dimensional

Investigation of the Weather Conditions During the Collapse of the Morandi Bridge in Genoa on 14 August 2018 Using Field Observations and WRF Model

Atmosphere, 2020
On 14 August 2018, Morandi Bridge in Genoa, Italy, collapsed to the ground that was 40 m below. This tragedy killed 43 people. Preliminary investigations indicated poor design, questionable building practices, and insufficient maintenance—or a ...

Investigating the Microphysical Characteristics and Environmental Influences of Warm‐Rain Precipitation in Fuzhou Region of China

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Microphysical characteristics of warm‐rain precipitation that occurred in Fuzhou region during warm seasons of 2022 and 2023 have been investigated by using polarimetric radar data. Results of a modified warm‐rain identification algorithm indicate positive ZDR variation in the liquid layer should be added as a criterion to prevent events ...

Assessing Downburst Kinematics Using Video Footage Analysis

Atmosphere
Measurements of downburst outflows using standard meteorological instruments (e.g., anemometers) are rare due to their transient and localized nature. However, video recordings of such events are becoming more frequent.
